asked

I’m taking a Z pack for a sinus infection and I’m on the last dose this evening. Within hours of taking the first two tablet doses, I had a cold sore on my top lip and now using only topical acyclovir, I know I have another one on my bottom lip opposite side. Is it common to get cold sores when taking a Z pack? I do not get them very often anymore. I do have valaciclovir I can take if it will help.
